SPECIES ASSOCIATED WITH BLACK-TAILED PRAIRIE DOGS

Black-footed Ferret This species is an obligate associate of prairie dogs because black-footed ferrets de- pend on prairie dogs as a primary food source and use their burrows as shelter from weather and predation. The black-footed ferret is completely dependent upon prairie dogs for survival. Prairie dogs constitute about 90% of the ferret's diet.

Swift Fox The swift fox is also native to the grasslands of the Great Plains region of North America. Prairie dogs com- prise a major part of the swift fox diet and swift fox rely on burrows for cover. The most limiting factor for swift foxes are competition with other predators, and the conversion of shortgrass prairie. The key com- ponent in the restoration of swift fox is the provision of suitable short grass habitat where they can obtain prey while avoiding predators .

Ferruginous Hawk Ferruginous hawks occupy a variety of habitat types. Breeding population declines of Ferruginous Hawks may be due to loss of primary species such as prairie dogs, rabbits, and ground squirrels, which can force hawks to look elsewhere for better nesting habitat . Reducing prairie dogs as a food source for Ferruginous Hawks could negatively impact agricultural practices, by re- ducing predation on other prey and rodent species that can impact agricul- ture.
